Environment
ThermoWood® - ENVIRONMENTAL ASPECTS
ThermoWood® is a responsible choice for sustainable construction and design. Its environmental performance is based on certified raw materials, a chemical-free production process, long service life and full recyclability. Because the production process of ThermoWood® is based only on the use of high temperature and steam, any harmful substances do not leach to the ground from products.
CERTIFIED RAW MATERIAL
The raw material used in the production of ThermoWood ® comes from sustainable sources.
Forest certification schemes include:
PEFC - Programme for the Endorsement of Forest Certification
www.pefc.org
FSC - Forest Stewardship Counsil
www.fsc.org
OLB - Origine et Légalité des Bois

LONG SERVICE LIFE
Thermal modification increases durability of wood and lengthens its service life in many end uses. Long service life reduces need of transportation and need of products that are environmentally doubtful.
MAINTENANCE CYCLE
Thermal modification improves stability of wood. Because of reduced deformation (swelling, shrinkage, warp) ThermoWood® is good base for coating. Resin is removed during thermal modification and does not penetrate through coating layer of applications. Coated surface of ThermoWood® keeps longer in good condition. Lengthened maintenance cycle reduces consumption of substances that are needed for manufacturing of coatings.
DISPOSAL
In the end of its service life ThermoWood® can be exploited in energy production or placed into the normal waste system like normal wood.
RERPLACEMENT
The visual appearance of ThermoWood® is similar to tropical hardwoods. In some end uses ThermoWood® can be used instead of non-sustainable wood species. Compensatory use reduces transportation and saves endangered forests.
EMISSIONS
The emissions of ThermoWood® in the surrounding indoor air are very low. Attached table includes the results of measurements of total volatile organic compounds (TVOC), formaldehyde, ammonia and carcinogens from thermally modified pine and spruce. Also, sensory evaluation was performed.
Used test methods:
- VOC: ENV13419-1, ISO/DIS 16000-6
- Formaldehyde: ISO/FDIS 16000-4
- Ammonia: RTESIS295
- Sensory evaluation: untrained panel. The panellists evaluated the acceptability of the chamber air in scale not acceptable (-1… -0,1) – acceptable (+0,1…+1).
The age of measured products were 3 days and 28 days.
